TYPE-CLEANING DEVICE.

SPECIFICATION forming part of Letters Patent No. 694,136, dated February25, 1902. Application filed October 4, 1901. Serial No. 77,521. (Nomodel.)

To all whom, it may concern:

Be it known that I, JAMES T. CAWTHORN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Type Cleaning Devices, of whichthe following is a'specification.

My invention relates to improvements in type-cleaning devices, and hasspecial refer- :o ence to that class which are applicable to typewritingmachines.

My object is to provide a type-cleanin g device which is simple ofconstruction, easily adjusted, and efficient in operation.

[5 Heretofore the cleaning of type has been effected usually by means ofa hand-brush or brushing mechanisms which have been of a construction socomplicated that a needless amount of time and energy were required toeffectively clean the type. In my invention is found a quick andefficient means for thoroughly cleaning the type, whereby the hands ofthe operator do not come in contact with the dirt on the machine, as inhand-brush cleaners, and at the same time does away with the slowoperation of both hand-brush cleaners and those cleaning devices, ashitherto provided, which are attached to the machine.

The preferred form of my device is shown in the accompanyingdrawings,]in which Figure 1 is a broken plan view of a Remin gtontype-writingmachine, showing my improved type-cleaning device inposition there- 5 on; Fig. 2, a broken section on line2 of Fig. 1,showing my improved type-cleaner in side elevation and the manner ofholding it in .place; Fig. 3, a bottom plan view of the device, and Fig.i a broken section on line 4 in Fig. 2.

A represents the head or brush portion of the type-cleaning device, fromwhich extends :a handle or stem 13. At the opposite side of the head Ais rigidly attached a clip C. The

*head A is provided with bristles A, which may extend obliquely from theunder surface -of the head. The handle B may be of any convenient form.The clip C in its preferred form approaches the shape of the letter S,550 having an outwardly-turned recess or socket C', which affords ameans of attachment, in

the present case, to the ribbon guide-bar D of the machine, and therecess C which provides a means whereby the clip is secured to the headA.

F represents one of the type-levers, carrying a type F, which is shownraised into contact with thebristles.

In using the device the clip C is passed at its socket C over the edgeof the ribbon-guide D, which it clamps to hold the head portion rigid,and the handle B rests upon the frame E beneath the carriage-shit tin grail, as shown which position causes the bristles A to be in the path ofthe moving type, causing the type when struck up by the type-levers tostrike against the bristles. When the bristle-clusters A are at obliqueangles to the surface of the head A, they will yield bodily upward underthe force of the blows from the type and return to their obliquepositions. They will thus operate effectively to clean the type withoutdanger of the bristles separating or becoming squashed down, as wouldhappen in time if the bristles were struck on end in their directlongitudinal line.

Although my improved device is intended more especially for use in placeof the usual hand-brushes as a temporary attachment to the type-writingmachine, it may when removed from engagement with the ribbon guide-barbe used as a hand-brush. The handle B is curvilinear to adapt it to thehand and render the device convenient for use as a hand-brush. Itfrequently happens that through neglect orotherwise the type becomes Icaked with ink or the like, which the mere striking of the type againstthe bristles would not dislodge.
